更新我的应用程序到targetSdkVersion 31后，相机不再加载。当点击cameraBtn时，如下图所示，我的应用程序显示警告"相机不可用"。导航器。相机未定义。我熟悉插件的用法，过去几年我一直在成功地使用它，但由于某种原因，现在我正在转向targetSdkVersion 31，它不再工作了。如果有人能给我指路，我将不胜感激!
document.addEventListener('deviceready', function() {
cameraBtn.addEventListener('click', function() {
if (!navigator.camera) alert("Camera unavailable")
else if (!navigator.camera.getPicture) alert(navigator.camera)
navigator.camera.getPicture(
function(imgData) { // success
},
function(msg) { // fail
},
{
quality: 60,
destinationType: Camera.DestinationType.DATA_URL,
sourceType: Camera.PictureSourceType.CAMERA,
mediaType: Camera.MediaType.PICTURE,
encodingType: Camera.EncodingType.JPEG,
cameraDirection: Camera.Direction.BACK,
correctOrientation: true,
targetWidth: 512,
targetHeight: 512
}
);
});
});

我可以解决这个问题，删除相机插件和添加ANDROIDX_CORE_VERSION 1.8.0建议在cordova-plugin-camera github
cordova plugin add cordova-plugin-camera --variable ANDROIDX_CORE_VERSION=1.8.0
之前包。json显示ANDROIDX_CORE_VERSION 1.6.+
